//_________________________________________________
/*
BEGIN_HTML
<p>
Holds configuration options for proof and proof-lite.

This class will be expanded in the future to hold more specific configuration
options for the tools in RooStats.
</p>


<p>
Access to TProof::Mgr for configuration is still possible as usual
(e.g. to set Root Version to be used on workers). You can do:</p>
<ul>
  <li>TProof::Mgr("my.server.url")->ShowROOTVersions()</li>
  <li>TProof::Mgr("my.server.url")->SetROOTVersion("v5-27-06_dbg")</li>
</ul>

<p>
See doc: http://root.cern.ch/drupal/content/changing-default-root-version
